The branch main has been updated by dim: URL: https://cgit.FreeBSD.org/ports/commit/?id=1c818faba7259c7176aa3f6717451a274bff7fc2 commit 1c818faba7259c7176aa3f6717451a274bff7fc2 Author: Dimitry Andric <dim@FreeBSD.org> AuthorDate: 2024-11-10 11:49:55 +0000 Commit: Dimitry Andric <dim@FreeBSD.org> CommitDate: 2024-11-10 12:08:40 +0000 science/dlib-cpp: fix build with libc++ 19 As noted in the libc++ 19 release notes [1], std::char_traits<> is now only provided for char, char8_t, char16_t, char32_t and wchar_t, and any instantiation for other types will fail. This causes science/dlib-cpp to fail to compile with clang 19 and libc++ 19, resulting in errors similar to: /usr/include/c++/v1/string:820:42: error: implicit instantiation of undefined template 'std::char_traits<unsigned int>' 820 | static_assert(is_same<_CharT, typename traits_type::char_type>::value, | ^ /wrkdirs/usr/ports/science/dlib-cpp/work/dlib-19.24.6/dlib/bigint/../unicode/unicode.h:718:19: note: in instantiation of template class 'std::basic_string<unsigned int>' requested here 718 | const ustring convert_to_utf32 ( | ^ /usr/include/c++/v1/__fwd/string.h:23:29: note: template is declared here 23 | struct _LIBCPP_TEMPLATE_VIS char_traits; | ^ This can be fixed by defining `unichar` as `char32_t` instead of `uint32` in `unicode.h`, and adding a serializer for `char32_t` to `serialize.h`.
